Abstract (en)
A retractable interdental brush of the present application includes an interdental brush, a retractable mechanism, and a handle. The interdental brush and the retractable mechanism are connected to drive the retractable mechanism, so that the interdental brush can be driven to extend from the handle to clean a gap between teeth. After use, the interdental brush is retracted into an accommodation space of the handle through the retractable mechanism, so that the handle can form a compact instrument box, which is very convenient to carry. The interdental brush of the retractable interdental brush of the present application may be a built-in interdental brush. When the built-in interdental brush is used for cleaning, a brush body may be first retracted into an elbow at a front end of a delivery device, an outlet of the elbow at the front end of the delivery device is pressed against the gap between teeth to be cleaned to push the brush body, and a working portion of the brush body extends from the elbow and enters the gap between teeth to clean the gap between teeth, thereby resolving a problem well that the existing interdental brush easily stabs gingival tissue due to a difficulty of alignment with the gap between teeth.
